Hi Jayme! I'm glad you like the idea of the removable hoop! My beds are 3' wide and the length of the PVC (1/2") pipes is 6' ; we used 1/2" pipes, since the walls of the pipes are not thick and in this way is easy to work with them. You can try with your beds, if they are wider, then the pipe must be a little longer. Just try with one, and when you get the high of the hoop you like, you can cut the pipe and use it as sample for the rest. Good luck and have fun!
